What are "jam-resistant" systems designed to do in military communications?

Jam-resistant systems are specifically designed to withstand electronic jamming attempts, which is crucial for maintaining reliable communications in a military context. These systems employ various techniques, such as frequency hopping, spread spectrum technologies, and other forms of signal processing to ensure that the transmission remains intact even when adversaries attempt to disrupt or block communication signals. By being resistant to jamming, these systems help ensure that military operations can continue effectively despite electronic warfare tactics employed by opposing forces. This resilience is vital for command and control, situational awareness, and overall mission success.
